This maneuver is a variation of "eights along a road" and
involves the same principles and techniques. The primary difference is
that at the completion of each loop of the figure eight the airplane should
cross an intersection of roads, or a specific point on a straight road
(Fig. 11-8). The loops should be across the road and the wind should be
perpendicular to the road. Each time the road is crossed, the crossing
angle should be the same and the wings of the airplane should be level.
The "eights" also may be performed by rolling from one bank immediately
to the other, directly over the road.
